中文摘要: 2013年3月4—9日上海地区出现了一次连续6 d的污染过程，本文利用PM2.5和PM10的小时监测资料、常规气象资料、激光雷达资料、FY 3A卫星监测资料及NCEP再分析资料，综合探讨了此次连续污染过程的气象特征，发现此次连续污染与天气形势的高低空配置有密切关系，槽后被西北气流控制，稳定的垂直层结及地面较弱的气压场，有利于污染物的积聚和污染天气的维持。文章还对此次连续污染过程中的重污染过程进行了深入的诊断分析，研究发现850 hPa及以上中低空西北气流将上游污染物输送至上海，再配合下沉运动沉降到地面，是造成此次重度污染过程的主因；同时，本地风力小、近地层垂直温度层结稳定等均不利于污染物在水平和垂直方向上的扩散，为污染物的积聚创造了条件。

Abstract:A continuous air pollution event which occurred in Shanghai during 4-9 March 2013 was investigated. The main features of air pollution transportation and formation were preliminary discussed by using the hourly observation data of PM2.5 and PM10, conventional weather data, data from the ground based Micro Pulse Lidar (MPL_4B), data from FY 3A satellite and NCEP (1°×1°) reanalysis data. The results show that the pollution event was mainly influenced by the weather condition in upper and lower levels. The northwest wind after the trough, the stable stratification and the weak pressure field made air pollutants difficult to disperse. The northwest wind at 850 hPa could transport the dust to Shanghai, and then the dust subsided to the ground surface. The faint wind and the stable temperature stratification near the surface provided favorable conditions for the formation and maintenance of the heavy pollution event.
